Abstract
A liquid level and density measurement device is disclosed. The device comprises an elongated magnetostrictive transducer and at least two transducer magnets embedded into floats that can freely move along a transducer. One float is relatively more sensitive to liquid density variation than the other float. The less sensitive float is used for liquid level measurement and the more sensitive float is used for liquid density measurement. The liquid density float has a lower part completely immersed into a liquid and an upper part partially immersed into a liquid. The upper part is made substantially in the form of a hollow cylinder with an internal diameter larger than the external diameter of the liquid level float. Therefore the liquid density float can move up and down without touching the liquid level float.
